Code Review

This pull request introduces a significant refactoring to align the vllm-ascend codebase with the upstream vLLM v1 API, particularly in the worker components. Key changes include refactoring InputBatch and BlockTable to inherit from their upstream counterparts, which reduces code duplication and improves maintainability. Additionally, it centralizes the management of Ascend-specific resources like mc2_mask, cos, and sin using global variables, moving away from passing them as parameters. The speculative decoding method deepseek_mtp has been generalized to mtp. Overall, these changes improve code structure and alignment with the main vLLM repository. My review has identified one high-severity issue related to an incorrect type hint that should be addressed.

[gemini-code-assist]

The type hint for _reserved_mc2_mask is Optional[int], but it is assigned a torch.Tensor of dtype=torch.bool in the set_mc2_mask function. This should be corrected to Optional[torch.Tensor] to accurately reflect the variable's type and prevent potential bugs.

Suggested change

	_reserved_mc2_mask: Optional[int] = None
	_reserved_mc2_mask: Optional[torch.Tensor] = None
